The latest instalment, Bill and Ted Face the Music, show a much older pair as they must go on a special mission to save the world.

Original stars Keanu Reeves and Alex Winter star once again, this time as middle-aged parents with wives, something few would have seen as possibilities for the pair.

This time, they go forwards in time to try and find their song which will create a Utopian world for their children.

The movie also featured their children, Billie and Thea (played by Brigette Lundy-Paine and Samara Weaving) who could be the ones to carry on the saga in a future film.
